Notice to Mainframe Submitters: Upcoming File Location Change

By the end of 2016, all files that are currently sent to the RDS Center Mainframe must be sent to a new location. This change only impacts Vendors and Plan Sponsors that submit data to the RDS Center Mainframe and does not affect participants that submit data using the RDS Secure Website. In the coming months, CMS’ RDS Center will be working with Vendors and Plan Sponsors that submit cost and retiree data to the RDS Center Mainframe to establish a new location for sending files.

Mainframe submitters are encouraged to visit the Mainframe Submission: File Location Change page on this website for an overview of the change, its impact, and a timeframe for activities leading up to the change.

If you need more information, contact CMS’ RDS Center.
